SPECIFICATION forming part of Letters f'atent No. 423,135, dated March 11,1890.

Application filed October 19, 1889. Serial No. 327,573. (No model.)

To aZZ whom, it may concern:

Be it known that I, EDWIN ORIPPEN, of New Orleans, in the parish of Orleans and State'of Louisiana, have invented a new and Improved Combined Water-Tower and EX- tension-Ladder, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved combined Water-tower and extension-ladder to facilitate the extinguish ing of fires, to enable firemen and other persons to climb to an elevation, and to conveniently support the persons at an elevation for observation and other purposes.

The invent-ion consists in certain parts and details and combinations of the same, as will be described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similarletters of reference indicate corresponding parts in all the figures.

Fig. 4 is an enlarged front elevation, with parts in section, of the packing and gland of the water-tower. Fig. 5 is a side view of the same with parts broken out. Fig. 6 is an enlarged plan view of part of the improvement in a folded position and with parts removed. Fig. 7 is a side elevation of the same with parts in section. Fig. 8 is an end elevation of the lower end of the water tower and extension-ladder in an extended and raised position. Fig. 9 is alike view of the upper part of the same. Fig. 10 is an enlarged side elevation of the upper end of the tower and ladder with parts in section. Fig. 11 is a sectional plan view of the same 011 the line 00 a: of Fig. 10. Fig. 12 is a front elevation with parts in section, showing the connection between two successive ladders and part of the water-tower. Fig. 13 isaside elevation with parts in section, illustrating the arrangement of the pipes and their valves and means for operating the same; and Fig. 14. is an enlarged plan view of the steering apparatus for the rear running-gear.

'lheinmroVement is preferably mounted on a truck A, provided with a front runninggear A and a rear running-gear A connected with each other by pipes A bent downward bet-ween the front and rear wheels to form a platform on which the water-tower is supported. A pipe A is located between the pipes A and extends from the front runhing-gear A to a cross-pipe A connecting the pipes A with each other near the rear running-gear A From the cross-pipe A extend rearward two pipes A terminating at the rear end of the rear running-gear A in line with the rear 'ends of the pipe A Each of the pipes A is provided near each outer end with a valve A for opening and closing the pipe at either end, and similar valves A are held in the front end of the pipe A and the rear ends of the pipes A. Next to the valves A are arranged suitable couplings for connecting the several pipes A A and A with hose running to a fire-engine or other suitable source of water-supply. The three pipes A and A are connected with each other near the middle by a transverse pipe A On the lower parts of the pipes A A and A between the front and rear running-gears A and A of the truck A, is held a turn-table B, provided with a platform B, supporting on its under side a ring B mounted to travel on a similar ring B secured on top of the pipes A and A Guide-blocks B are fastened to the under side of the platform 13' and extend under the fixed ring B so as to hold the turntable B in place on the rim B Friction-rollers B are mounted to turn in the ring B and travel on top of the ring B so as to reduce friction to a minimum when the turntable B is turned into a right angular position with regard to the pipes A and A. In the ends of the platform B of the turn-table B are held the legs 13, adapted to rest on the ground when the turntable is turned into an angular position and adapted to be supported in an uppermost position when the turn-table is in its normal position. A suitable. bolt or look B (see Fig. 7) is employed to hold the legs B in the two different positions above mentioned.

Near one end of the platform B of the turn-table B are secured the bearings 0,111

which are mounted to turn the trunnions formed on a cap G on which is fastened the lower end of the exterior pipe D of the watertower E, which is composed, principally, of the telescoping pipes D, D, D D and D, as shown in the drawings; but any number of such telescoping pipes may be employed.

On the rear end of the platform B of the turn-table B are secured the forwardly and upwardly inclined cylinders F, held in place by suitable braces secured to the turn-table platform B. (See Figs. 8 and 7 In each of the cylinders F is held to slide a piston F, provided with an outwardly-extending hollow piston-rod F passing through a suitable gland G. (Shown in detail in Figs. 4 and 5.) Each of the glands G is made of a split ring provided on its lower end with a screw-thread screwing in one of the cylinders F, and from the ends of the rim project the lugs G and G connected with each other by a screw G adapted to be turned by a suitable handle G,

' so that the split ring may be loosened or tightened on the hollow piston-rod F so as to prevent anyleakage and to fasten the pistonrodin place when it is extended. The two hollow piston-rods F of the cylinders F are connected with each other on their outer ends by a cross-bar F pivotally connected by the links. F with the trunnions F formed on the links F bolted on the exterior pipe D of the water-tower E. When the latter is in a folded position, the pistons F in the cylinders F are in their lowermost position, and when the pistons are moved outward, by means hereinafter more fully described, then the links F 'pull on the trunnions F and raise the watertower E into a vertical position, said watertower swinging on the trunnions O in the fixed bearing 0, held on the turn-table B. WVhen the tower E has been erected, the bolts or screws G of the glands G are screwed up by turning the handles Gr so that the glands G bind on the pistons F and hold the latter in place.

Into the lower ends of the cylinders F F open the ends of the transversely-extending pipe l-I, connected with a branch pipe H, in which is held a three-way valve H adapted to connect the said pipe H with the branch pipe H, and also to connect said pipe H with a short outlet-pipe H opening into the outer air. From the branch pipe H extends upward a short pipe H leading to a three-way valve H adapted to connect said pipe H with an outlet-pipe H opening to the outer air, or with a pipe H leading into a U-shaped pipe H connected at its ends with the upper ends of the cylinders F. In the pipe H in front of the short pipe H is held a valve 11", and the said pipe H is connected with a transverselyextending pipe I, held over the center of the turn-table B and provided 011 each side of the pipe H with valves 1 and 1 respectively. The valve 1 is adapted to connect the pipe I with the outer air, and the Valve 1 is adapted to connect the pipe l with a pipe 11, containing a valve 1, from which extends an outletpipe I. The pipe I also connects with a ,fiexible hose 1 leading to a pipe 1 opening into the cap 0, supporting the lower end of the exterior pipe D of the water-tower E.

From the pipe I extends downward a short pipe 1 opening into the cross A of the transverse pipe A, connecting the pipes A with the central pipe A The latter is connected with reservoirs J and J by means of the pipes J 2 and J each of which carries a valve J The reservoirs J and J extend longitudinally and are secured by suitable brackets to the under side of the fixed ringB supported by the pipes A and A as previously mentioned. The short pipe I is adapted to turn in suitable bearings formed in the cross A, as is plainly shown in Fig. 13, so that as the turn-table B is turned the connection between the pipe I and the cross A", and consequently the connection with the pipes A and A, is unaltered.

The reservoirs J and J are charged with a suitable compressed air, which can be admitted into the central pipe A from the latter into the pipe I, then into the pipe H, through the three-way valve 11*, and into the pipe H, so as to pass from the latter into the lower ends of the cylinders F. The compressed air, acting on the pistons F in the said cylinders F, forces said pistons outward,-

thus moving the tower into a vertical position, as previously described. VVhe-n this takes place, the valve H closes the pipe H and connects the pipe H with the outlet H, so that air in the upper parts of the cylinders F can escape to the outer air by passing through the pipe H into the pipe H through the three-way valve H into the outlet H and to the open .air. When the positions of the valves 11 and H are reversed, the said threeway valve I-l closes the pipe H and connects the pipe H with the outlet H The threeway valve H then connects the pipe H with the pipel-l and the compressed air passing through the pipe I into the pipe H passes from the latter through the pipe H and the three-way valve H into the pipes H and H so that the compressed air acts on the top of the pistons F in the cylinders F, thus foreing the latter downward and thereby lowering the tower E.

The valves H and H are operated simultaneously by a mechanism K under the control of the operator. The mechanism K comprises a lever K, fulcrumed on a suitable bracket on the platform B of the turn-table B, and is pivotally connected at opposite sides of its fulcrum with the links K and K of which the link K is pivoted to an arm K secured on the valve-stem of the threeway valve Hiwhile the other link K is pivotally connected to an arm K held on the valve-stem of the threeway valve H When the lever K is in the position shown in Fig. 13, the three-way valve II connects the pipe H with pipe H, and the three-way valve I1 connects the pipe H with which carries suitable packing, on top of which is held a gland G, similar to the one previously described. The gland G screws in the respective head, as is plainly shown in Figs. 4 and 5, and when the respective pipe is extended it can be fastened in place on the next lower one by turning the handle Or, so as A to press the split gland Gtogether, thus binding the extended pipe.

On the head L on the upper end of the exterior pipe D is secured a platform N, provided with a recess N,through which passes the extension-ladder 0, made of a series of sections P, P, P P and. P of which the latter or outermost section is secured at its upper end to a platform Q, fastened on the upper end of the interior pipe D of the tower E. The first ladder-section P is secured at its upper end to the platform N and at its lower end to the lower part of the exterior pipe D. The sections P, P P and P diminish in width, as is plainly shown in Fig. 11, and the said sections are guided in braces R, R and R secured to the heads L, L and L respectively. Near the upper end of each side of each ladder-section P P, P, and P is secured a staple S, adapted to be engag'ed by a correspondingly-shaped hook S, secured to the sides of the ladder-sections P", P P and P, respectively. In the outer ends of the brackets R ,R and R screw the screws R adapted to engage corresponding apertures formed in the plates P secured 011 the sides of the ladder-sections PgPf, P and P, when the said sections are extended.

In order toease the sliding movement of the several sectionswhen extended, the ladder-sections P P and P are held loosely in place in their respective brackets R R and R by transversely-extendin g rods R passing in rear of the upper ends of the said sections, asplainly shown in Figs. 10 and 11. By withdrawing the rods R the several ladder-sections P I P may be easily removed for repair when necessary.

The top platform Q on the upper end of the interior pipe D is provided with a suit able railing Q. From the upper end of the interior pipe D extends a short pipe T, from which diverge the branch pipes U, and U, each of the latter being provided with an or dinary valve U To the outer ends of the pipes T, U, and U may be coupled ordinary nozzles turned in any direction by the firemen standing on the top of the platform Q.

In the pipe T is held. a valve T, connected at the outer end of its valve-stem T by a link T with one arm of a bell-crank lever T, to which is secured a rope T extending tothe ground. In the other arm of the bell-crank lever T is formed a slot engaged by the outer end of a piston-rod T extending into the cylinder V, held on top of the platform Q. On the inner end of the piston-rod T in the cylinder V is held a piston T, on which presses a spring T coiled around the piston-rod T and serving to press said piston and its rod downward.

Into the upper end of the cylinder V leads a short branch pipe V, opening into the pipe T below its valve T. The valve T can be opened from the ground by pulling on the rope T ,so that the bell-crank lever T swings outward and by its link T pulls the valvestem T carrying thevalve T, outward. When the operator releases the pull on the rope T the valve T seats itself automatically by the action of the spring T pressing the piston T and the rod T downward. It will be seen that the fluid passing-through the pipe T also passes through the short branch pipe V into the cylinder V and on top of the piston T so that the pressure of the spring T on the piston is in excess of the pressure of the fluid agaipst the valve T, so that the latter closes by the action'of the spring.

The rear running-gear A of thetruck A is provided with a steering apparatus W. (See Fig. 14.) The axle of the rear running-gear is made in two pivoted sections WV and W each of which is provided at its inner end with a segmental gear wheel W or W, re spectively, both meshing at opposite sides into a worm-wheel of right and left threads W secured on a shaft WV, mounted to turn in suitable bearings in the rear running-gear A The shaft WV extends inward, and is connected by a universal joint WV with a shaft WV slightly inclined upward and mounted to turn in suitable bearings on the rear running-gear A On the upper end of the shaft W is held a hand-wheel W, adapted to be turned by operators located in seat-s arranged in front of the rear running g'ear wheels between the pipes A and A as is plainly shown in Fig. 2. It will be seen that when the operator turns the hand-wheel W the shafts \V and V turn and impart a like motion to the worm W which turns the segmental gear-wheels W WV, so as to swing the 'axle sections W and W simultaneously in opposite directions, whereby one of the wheel turns outward and the other inward.

The operation is as follows: The reservoirs ,J and J are provided on one end with asuitable inlet J so as to permit of charging the reservoirs with compressed air to double the amount necessary to extend the tower E to its extreme height. A small air-pump mounted on the apparatus or other suitable device may be connected with the inlet J in order to charge the reservoirs .T and J. The press- IIO ure in the reservoirs is to be constant at all times, and consequently it is necessary to connect the air-pump frequently and work it V long enough to compensate for the loss of pipes J 2 and J 3 into the central pipe A and from the latter through the cross A into the pipe 1 and from the latter to the pipe I, into the pipe H, through the three-way valve H into the pipe H, and from the latter into the cylinders F, so that the pistons in the sameare moved outward and the folded tower E is thrown'in a vertical position, as previously described. When the exterior pipe reaches a vertical position, then the outer ends of the trunnions F strike against the lugs F on the upper ends of the cylinders F, thus preventing further movement of the exterior pipe D.

Suitable bolts or other devices may be employed to fasten the outer ends of the trunnions F to the lugs F so that the tower is retained in a vertical position independently of any pressure against the pistons F in the cylindersF F. The operator now ascends the outermost section P of the ladder to the platform N, as shown, and loosens the screw G on the gland G on the upper end of the pipe D so that the interior pipe D is free to slide outward. The operator on the ground now opens the valve 1 in the pipe I, while the valves 1 and I remain closed. The compressed air in the pipe I can now pass into the pipe I, from the latter through the pipe I into the pipe 1 and from the latter into the cap 0, from which the air travels through the telescoping pipe and exerts its pressure against the loose pipe D so that the latter "slides outward out of the pipe D carrying along the outermost section P of the extension-ladder O. The pipe D and the extension-ladder P continue to ascend until the hooks S on the said sec tion P hook into thestaples S, secured near the upper end of the section P thus stopping all further movement of the pipe and ladder, as the said section P cannot move upward on account of the lugs IR. abutting against the under sides of the brackets R secured to the head L 'of the next following pipe D This latter pipe is held in place by the gland G on the pipe D and in a similar manner the pipe D is held on the pipe D, and the latter by the gland G on the pipe D. It will be seen that as the ladder-section P is guided in the bracket R a rotary motion of the telescoping pipe D is prevented when the ladder is extended, as above described. WVhen the pipe D has been extended, the operator, standing on the platform N, tightens the gland G, so as to lock the extended pipe D to the head L of the pipe D When the ladder-section P is extended, the operator screws the bolts R on the bracket R inward, so that the said bolts engage the apertures in the plates P whereby the laddersection P' is secured to the outer end of the bracket R and thus both the extended pipe D' and the extended ladder-section P are locked in place. The next lower pipe D is now extended as soon as the operator loosens the clamping-screw G3 of the gland G, held in the head L of the pipe D The pressure of the air in the t elescoping pipes now forces the pipe D outv d, so that the said pipe carries along wit it the ladder-section 1? until its hook S e ages the staple S of the next following ladl -section P The abovedescribed operatic is then repeatedthat is, the gland G in the head L is operated on, so as to lock the extended pipe D in place,

and then the screw R in the bracket R is screwed in to lock the extended section P in place. This operation is repeated with the other extension-pipes D and D until the latter, as well as the ladder-sections l? and P, are extended and locked in place. When the tower has been erected and the ladder.- sections extended, then the operator on the ground closes the valves J in the pipes J and J so as to prevent further escape of the compressed air from the reservoirs J and J. The operator also closes the valve H in thepipe 11. During the erection of the tower other members of the fire'company attach hose connected with engines or other sources of water-supply to either of the pipes A A or A so that when the respective valve A in the connected pipe is opened a stream of water will flow through the said pipe into the cross-pipe A", and from the latter through the short pipe 1 into the pipe I, through the same into the pipe I, the flexible hose 1 the pipe 1 to the cap 0, and from the latter into the several pipes D, D, D D and D of the extended tower E. Operators meanwhile have climbed up the several extensions of the ladder'O to the platform Q and attached the usual flexible nozzle or playpipe to the pipe T, so thatwhen the valve T is opened the water forced by the engines through the apparatus will pass out of the flexible nozzle or play-pipe. In case the nozzle was previously attached, then the valve T can be opened from the ground by pulling on the rope T. It will be understood that the compressed air used for the erecting the tower escapes in advance of the water as soon as the valve T is opened, the tower standing valves U opened, so that water passing through the tower may be divided into three streams. The operation of lowering the tower is the reverse of extending it, the operators first closing the valve T and shutting off the water-supply, so that the tower remains filled with water. The gland G 011 the exterior pipe D is slacken'ed and the screw R on the platform N is unscrewed from the plate 1? of the section P, after which the valve I in the pipe I is opened, so that water can escape through the outlet 1 The telescoping pipe D now descends until it reaches its innermost position, the next gland G on the head L is then slackened, and the screw R in the bracket R is screwed from the section P so that the next pipe D can descend in the pipe D. The above-described operation is repeated on the several pipes until all have descended to their lowermost position. When the water has run out through the outlet I the valve I is closed. The tower can then be lowered by the operator first removing the fastening between the lugs F and the ends of the trunnions F and then moving the lever K in the direction of the arrow 00, so as to change the positions of the three-way valves H and H after which the valve H is again. opened, as are also the valves J 4 in the pipes J 2 and J connecting the reservoirs J and J with the pipe A The air in the cylinders F can now escape through the pipe H, the three way valve H and the outlet H to the open air, and air under pressure passes from the reservoirs J J through the three way valve H into the pipe H and from the latter through the pipes 1-1 to the upper ends of the cylinders F, thus forcing the pistons F downward, whereby the tower is lowered, as previously described. The operator handling the lever K can lower the tower very rapidly or slowly, according to the positions of the valves H and H permitting a rapid or slow escape of air from the lower ends of the cylinders F and a rapid or slow inlet of compressed air through the three-way valve H into the upper ends of the cylinders F.

In case the tower is used without a fire-engine and has not sufficient'air-pressure to lower it, it can be lowered by the glands G in the cylinders F by slacking the bolts in the said glands'to just permit the piston-rods F to slide slowly inward by the weight of the tower.

In case the device is used as an extension ladder and the reservoirs are charged with a compressed air, the operation of erection and extension is about the same as before de scribed, with the exception that canvas hose is fastened on each side of the tower on top and secured. to the railing Q 011 the platform Q. The tower and ladder are then extended. to the height necessary to reach either a win dow or the roof of a building. The hose attached to the railing Q can be led across the roofs of buildings and used to throw a stream.

The extensioirladder can be turned in any desired direction by the operatortaking hold of the legs B, so as to turn the turn-table B until it stands at angles to the pipes A The legs B are then let down to the ground and fixed by any ordinary means, so as to steady the platform B. The tower and the extension-ladder may then be inclined by the operator handling the lever K ,so that the upper part of the extension-ladder or tower may lean against the building, thus forming a means of communication from the upper part of the building to the ground.
